Faust has also had SOUL support for a while. Not sure what's new over there but maybe Stephane will see this and comment :)
On licensing, how will it work for creators of open source hardware? Will they still need to pay a licensing fee if they are targeting a specific device with closed driver IP? Or could there be an exception there?
Do you also see yourselves supporting open low-level hardware (RISC-V, FPGA, ...?), and in that case would you consider opening your driver IP for those targets?
RISC-V is an easy one to support, as our JIT uses LLVM so it's just a case of adding a build flag for that.
FPGA is more interesting. I think there could be some really clever tricks we can do for soul programs which are highly parallel, but that kind of rocket-science stuff is probably going to have to wait until we have a couple of PhD students to work on it :)
A lot of people have been down this road before, and it doesn't end well for the users.
At least your lawyers are happy.
